I am pretty sure that it represents the "wheel of fortune" that raises a  man up and then casts him down.  It's a common medieval motif, but it usually has people on the wheel, and "Fortune" herself turning the crank. 
An image search for   wheel of fortune medieval   will bring up quite a few examples.
